storing values in variable and print them using PHP

Is it possible to do something like this? I'm new to this so don't know!

//row 1 in mysql array
$var = "hello"; 
$id = 1; 

//row 2 in mysql array
$var = "bye";
$id = 2;

//Closing while loop

//Is the following possible?
echo $var1; //outputs "hello"
echo $var2; //outputs "bye"

// Define them both as arrays
$var = array();
$id = array();

// In your loop
$var[] = "hello";
$id[] = 1;

// Next iteration
$var[] = "bye";
$id[] = 2;

// Printing them out
echo $var[0]; // prints out "hello"
echo $var[1]; // prints out "bye"

Using arrays^^

Alternatively:

$rows = array();

// In your loop
$rows[] = array("id" => 1, "var" => "hello");

// Next iteration
$rows[] = array("id" => 2, "var" => "bye");

// Print them out
echo $rows[0]["var"]; // Prints hello
echo $rows[1]["var"]; // Prints bye

You mention MySQL. So a more complete example of what you want to achieve would be:

$var = array();
$id  = array();
while ($row = mysql_fetch_assoc($result)) {
    $var[] = $row['text']; // don't know how the column is named
    $id[]  = $row['id'];
}

echo $row[0]; // hello
echo $row[1]; // bye

With a looping variable i:

$var = array();
$i = 1;
while ($row = mysql_fetch_assoc($result)) {
    $var[$i] = $row['text']; // don't know how the column is named
    $i++;
}

echo $row[1]; // hello
echo $row[2]; // bye

I would do so

$id = 1; 
$var[$id] = "hello";
$id = 2;
$var[$id] = "bye";
echo $var['1']; 
echo $var['2']; 
// or
echo $var[$id];

Not like you want, you can use an array though:

$var[1] = "hello";
$var[2] = "bye";

echo $var[1];
echo $var[2];
